The selectivity or sharpness of series resonant circuit is measured by quality factor or Q factor.It is defined as the ratio of the voltage across the coil or capcitor to the applied voltage.In other words it refers to the sharpness of tuning at resonance.
Q = voltage across L or C ( in volts) / applied voltage ( in volts )
Q = 1/ R * ( L/C)^ 0.5
Q is just a mere number having values between 10 to 100 for normal frequencies.So it has no unit. Circuit with high Q values would respond to a very narrow frequency range and vice versa.Thus a circuit with high Q value is sharply tuned while a circuit with low Q value has a flat resonance.Q factor can be increased by having a coil of large inductance but of small ohmic resistance.

How many amp in a kva?
If it's a simple resistive circuit, or a D.C. circuit, 1 kVA = 1 kW. Generally, it depends on your power factor. Since real power, P, is equal to the total power, S, multiplied by the power factor, p.f. Power factor is the cosine of the angle between the current and the voltage, O. So, P = S * cos(O)
What is discrimination factor of electrical circuit protection?
Electrical discrimination is to do with selecting the correct protection in the fault path of an electrical circuit. To illustrate, if you have a machine at the end of an electircal circuit and that is protected by a 13A fuse lets say, and then you have a 20A circuit breaker protecting that at the consumer unit (fuse board), and then the main switch on the consumer unit is a 10A circuit breaker, then every time the machine uses more than 10A of power the main switch will trip and disconnect everything connected to it, that is where discrimination is not achieved. Basically it is where the circuit protection closest to the macine is smaller and it gets bigger as it goes boack to the source, then discimination is achieved. I hope that helps. If not then it probably need a drawing to help answer.
What is the unit for measuring the rate of electron flow in a circuit?
Electron flow is known as current. SI unit is Ampere

unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance
What unit is used for counting electrons in a circuit?
Moving - amperes. Stored - coulombs.
Which actually does work in circuit voltage or current?
Power (energy per time unit) actually depends on both. In a DC circuit, it is the product of voltage and current. In an AC circuit, it is the product of voltage x current x (power factor). The power factor is often close to 1.
Are 3 watts equal to 2 amps?
Watt is the unit of power and amp is the unit of current,power in DC circuit is product of volthe and current but in AC circuit it is the product of voltage and currentand power factor ie P=VIcos phi
How can one stop a portable AC unit from shutting off the circuit breaker?
Don't overload it. Your circuit may not be large enough. If it is 15 amps at 110 volts I'd bet that's it. If it shares a circuit with lights or other equipment that may be a major factor also.
Where is the low fuel module in a 1989 Mustang and would it effect the reading of the fuel gauge?
it is with the fuel sending unit and is in series with the circuit that powers and measures the resistance on the sending unit via the float on the sending unit.

How do you convert large unit into a small unit?
Multiply by the factor for converting the large unit to the small unit or divide by the factor for converting the small unit to the large unit.
What is the difference between Kilovolt Ampere and Kilowatt?
A kilowatt is an unit of true power in an AC circuit -as measured by a wattmeter. A kilovolt ampere is an unit of apparent power in an AC circuit, which is the product of the voltage across a load by the current through it. The relationship between the two is: kilowatt = (kilovolt ampere) x (power factor of load)
